PROPELLING AND STEERING APPARATUS FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 366,849. dated July 19, 188'7 Application filed January 5. 1886.

To all whontjt nury concern:

Be it known that I, CARL OHRISTOPH LUD- WIG LUOHT, a subject of the King of frussia, residing at Colberg. in the Kingdom ofPrussia, Germany, have invented new and useful Imratus for Vessels, Boats, and the Like; and I do declare that the followingis atrue and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference'marked thereon, and being a part of this specification.

This invention relates to certain new and useful improvements in that class of propelling devices in which pairs of hinged wings are used, which automatically separate when moved in one direction and swing together when moved in the opposite direction.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a rear view of a vessel provided with my improved propelling device, parts being in section. Fig. 2 is a sectional plan view of the same. -Fig. 3 is a side view of the same. Fig. 4 is a plan view. Fig. 5 is an enlarged face view of the propelling device, parts being broken out. Fig. 6 is a plan View of the same, parts being broken out.

The vessel is provided with a steam or air motor of any system, which is not shown. The motor revolves a crank-shaft, A, on the deck, which is connected by the rods B and O with an arm of a disk, D, mounted on the upper end of the shaft E, journaled vertically in the rear part of the vessel. On the lower part of said shaft the arms F are secured, which project from opposite sides of the shaft, and are suitably stiffened and braced. .In said arms F the vertical shafts G are journaled, on the end parts of which the arms I are mounted to swing toward and from each other, and in the swinging ends of said arms the shafts K are mounted to turn, and on said shafts the wings or flaps H are mounted, which are connected by hinges at L. As shown in Fig. 6, the two wings or flaps H of the same shaft, G, are in the same plane, and press with their entire surface against the water when the-shaft E revolves in the direction of its arrow, Fig. 6. \Vhen the said shaft E turns in the inverse di- Scrial No. 187,684.

rection, the wings are swung together and this position, the wings can pass through the 2 water very easily, as they offer no resistance. provements in Propelling and Steering Appa- In order to avoid the counter-pressure of the water when the wings are swung together, guard-plates M are applied, which are riveted at their upper and lower parts to the arms I. During the backward movement of the wing mechanism the water exerts a pressure only against the outside or exterior halves of the flaps or wings H, and thus the closing of the same is facilitated.

To further facilitate the closingof the wings, a spiral spring or a platespring, N, is provided,which presses against the outside halves of the wings, and which is in tension when the wings act against the water. When the pressure against the water ceases, the springs N press the wings H together, and they are then completely folded by the pressure of the water. Vhen the direction of movement of the vessel is to be reversed the win s H must be reversed, which is accomplished in the following manner: Upon the upper deck the handwheel 0 is mounted, from which the shaft Q, carrying a sprocket-wheel, can be revolved by means of the chain P.

The cog-wheel R on theshaftQ engages with the cog-wheel R on the shaft S, mounted on the disk D and carrying the two bevel cogwheels TT, engaging with the bevel cog-wheels T T on the two vertical shafts U U, mounted in bearings V V on the shaft E. By means of the cranks \V XV, Fig.6, and the rods X X, the motion is transmitted from the shafts U U to the racks Z Z, mounted to slide on the arms F F. Said racks engage with cog-wheels Z Z on the shafts G, which wheels are provided with the armsYY, which, when the wheels Z Z revolve, bear against the arms I I and turn the flaps or wings H one hundred and eighty degrees.

The direction of the vessel can thus be reversed without reversing the engine, and the vessel can he stopped much more rapidly than a vessel provided with paddle-wheels or a screw.

The course of the vessel can also be regulated and controlled from the upper deck.

The hand-wheel o is provided with a pointer,

which shows the inclination of the flaps or wings on a suitable plate.

In order to permit of turning the wings when the vessel is in motion, the teeth of the wheels R and It are made round, and the contact-point of the two pitch circles of said wheels is on line with the axis of the shaft E.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a mechanism for moving and steering vessels, the combination, with the hingedtogether wings mounted on shafts carried by arms supported upon a common shaft arranged on transverse arms connected to a central shaft, of springs arranged to press upon the inner or rear sides of the said hinged-together wings,

substantially as and for the purpose set forth. 2. In a mechanism for moving and steering vessels, the combination, with the shafts G, supported in arms F of a shaft, E, and carrying pinions Z,engaging with racks, of-the arms I, connected to said shafts G and carrying hinged-together wings H, and mechanism for actuating said racks, substantially as and for the purpose set forth.

3; A mechanism for moving and steering vessels, consisting of wings H, vertically arranged one near the other and hinged two by two, each of which wings turns on a vertical shaft, K, mounted nearly in the center of each wing, and provided on its upper and lower ends with fixed arms I, the arms of one pair of wings being loosely mounted on a common vertical shaft, G, supported by horizontal transversearms F, which are mounted on a vertical shaft, E, placed between the sternpost and rudder-post, and which arms F have a rocking motion on the said shaft E,'the pairs of wings. pressing with their whole surface against the water when they move in a direction opposite to that of the vessel, while when moving in the same direction as the vessel they clap together and offer a decreased resistance to the water, substantially as set forth.

4. A mechanism for moving and steering vessels, consisting of transverse arms, in combination with toothed wheels provided with v rounded teeth and connected to a rocking shaft, the disposition of said wheels being such as to form an angle with each other,while at the same time being rotatable around their shafts, said shafts being journaled in such manner that the point of intersection of the toothed wheels falls within the axis of the shaft, and the driving-wheel is fixedly journaled,while the driving-wheel is supported by bearings on the shaft and rotates therewith,

substantially as herein shown and described.

5. In a mechanism for propelling vessels, the combinatiomwith avertical shaft, of transverse arms on the same projecting from both sides of the shaft,- vertical shafts mounted to turniu the arms, the shafts G on the said arms,
